Spontaneous imbibition of water-based fracturing fluids into the shale matrix is considered to be main mechanism responsible for high volume water loss during flowback period. Understanding capacity and rate helps determine fluid volume, optimize design, analyze influences on production gas. Imbibition experiments were conducted samples from Sichuan Basin, some tight sandstone Ordos Basin. Tight volcanic Songliao Basin also investigated comparison. The effects porosity, clay minerals,...
The exploitation of shale gas has been a hot topic, and the understanding water occurrence pore size distribution in reservoirs plays crucial role efficiently developing this type resource. In study, we target moderate-shallow marine shales from Lower Cambrian Niutitang Formation deep Silurian Longmaxi Formation. Low-field nuclear magnetic resonance is applied to investigate together with complementary experiments including mineral component analysis, scanning electron microscopy (SEM),...
After flowback, the residual fracturing fluid will reduce gas seepage space and influence natural production, which attracts widespread attention. In this study, irreducible water saturation was investigated, its controlling factors were clarified. We target Upper Paleozoic Taiyuan Shihezi Formations, belong to a tight reservoir in eastern Ordos Basin. The main experiments include porosity, permeability, mineral composition, nitrogen adsorption, mercury intrusion porosimetry, nuclear...
The nanometer-scale architecture of organic matter (OM) and associated pores in highly mature gas shales from the lower Silurian Longmaxi Formation upper Yangtze platform south China were investigated using field emission scanning electron microscopy (SEM), focused ion beam SEM, low-pressure (N2 CO2) adsorption bulk pore characterization. shale comprises fine-grained siliciclastic rocks deposited a marine shelf environment, which was dominated by quartz clay minerals. Four porous OM types...
Rock fabric and its influence on residual oil distribution are key issues to the highly efficient development of shale oil. This study targeted rock distribution, samples were selected from first second members Upper Cretaceous Qingshankou Formation in Songliao Basin. Multiple methods used analyze fabric, including material composition, scanning electron microscopy (SEM), micro-computed tomography (micro-CT), low-temperature nitrogen adsorption (LT-NA). The was investigated by extraction...
Diatoms are critical indicators in marine paleoecology and contemporary ecosystem studies, yet the accuracy of diatom analysis depends on effective purification methods. Current screening techniques often yield low accuracy. This study introduces a multi-stage method that integrates both physical chemical to enhance extraction remains from sediments, thereby improving reliability subsequent analysis. Using surface sediment samples Pacific Ocean, we compared effectiveness three methods: heavy...
The ocean is a significant global reservoir of uranium (U) and thorium (Th). These elements can be incorporated into marine sediments through processes involving organic matter (OM), redox conditions, terrigenous inputs, mineral interactions. Helium generated the radioactive decay U Th within geological formations represents critical potential resource. Marine black shales, which are rich in Th, widespread Ediacaran Doushantuo Formation Upper Yangtze Platform, making them key target for...
Nowadays, given the lack of resources that is threatening globe, exploitation and exploration oil/gas, especially unconventional reservoirs, has become a priority [...]
A series of methane sorption isotherms were measured at 303 K, 313 323 333 and 343 K pressures up to 12.0 MPa for two shale samples from the Upper Triassic Chang 7 Member in southeastern Ordos Basin with total organic carbon content values 5.15% 4.76%, respectively. Both Langmuir- Dubinin–Radushkevich-based excess models found well represent within experimental pressure range. The maxima absolute capacity fitted by both are not significantly different. In current study, effects temperature...
To research the imbibition behavior of shale reservoirs, experiments were conducted. However, clay-rich has small particle detachment during imbibition, which causes conventional method failure. A novel was proposed to deal with this problem and investigated. In method, apparent imbibed volume increases quickly at initial time decreases sharply late because detaching from sample. This phenomenon happened even though samples coated epoxy resin, indicated that clay strong swelling property....
We have used focused ion beam-helium microscopy and low-pressure [Formula: see text] adsorption to investigate the pore characteristics of Lower Silurian Longmaxi shale. These results, combined with molecular potential energy theory, reveal relationship between size occurrence state shale gas. Our results that (1) volume specific surface area are mainly contributed by pores diameters less than 10 nm. Nanoscale organic-matter predominant, is not generally smooth has fractal characteristics....
